A
radiation threat, commonly referred to as a "dirty bomb" or
"radiological dispersion device (RDD)", is the use of common
explosives to spread radioactive materials over a targeted area. It is
not a nuclear blast. The force of the explosion and radioactive contamination
will be more localized. While the blast will be immediately obvious, the
presence of radiation will not be clearly defined until trained personnel
with specialized equipment are on the scene. As with any radiation, you
want to try to limit exposure.
If There is a Radiation Threat or "Dirty Bomb"

To limit the amount of radiation you are exposed to, think about shielding,
distance and time.

* Shielding: If you have a thick shield between yourself and the radioactive
materials more of the radiation will be absorbed, and you will be exposed
to less.

* Distance: The farther away you are away from the blast and the fallout
the lower your exposure.

* Time: Minimizing time spent exposed will also reduce your risk.
As with any emergency, local authorities may not be able to immediately
provide information on what is happening and what you should do. However,
you should watch TV, listen to the radio, or check the Internet often
for official news and information as it becomes available.
